17-7PH, AISI 631, X7CrNiAl17-7, 1.4568 - specification and application
Stainless steel from the group of age-hardened PH with the highest content of Chromium - 17% and Nickel - 7% in relation to PH of grades 15-5 and 17-4. It has excellent strength properties, high hardness and elasticity, good corrosion resistance and resistance to high temperatures and deformation.
In terms of chemical composition, the corrosion resistance equals that of AISI 301 / 1.4310 steel, in terms of mechanical properties it is a much better choice for responsible parts and components exposed to fatigue. In the annealed state, the steel has an austenitic structure, after heat treatment of ageing it turns into martensite, increasing its strength properties along with obtaining magnetic properties.
The material is used on valve parts, tanks, springs, spring washers, food knives, diaphragms, low and high temperature parts, heat exchangers, special fittings and installations, machine constructions and components. Steel is intended for the aerospace, petroleum, chemical and petrochemical industries, energy, food and cryogenic industry in the form of strips, wires, sheets and bars.
